BOTTLE STOPPER AND POURER Filed June 20. 1950 IN VEN TOR. SAvEmo A- RENZI Patented June 16, 1953 UNITED STATES PATENT OFFICE BOTTLE STOPPER AND POURER Saverio Renai, Jersey City, N. J. Application June 20, 1950, Serial No. 169,107

This invention relates to new and useful improvements in dispensing attachments for liquid containers, as liquor bottles, and, more particularly, the aim is to provide a novel and valuable unit of the kind comprising a stopper for such a bottle, a pouring spoutforming part of a structure sleeved by said stopper with the latter of cork or the like andof tubular or annular form, and a vent tube also forming part of said structure. f

The principal object of the invention is to minimize the cost of manufacture of a device as above, yet to produce thesame in an assembly of the component parts such that important improvements are attained in regard-to ruggedness and durability of construction as well as in regard to dependability of operation.

As the invention is preferably carried out, for attainment of the above and other objects, the

spout, as the main structure of the unit, is rolled up from a single sheet metal blank, also, while the spout is thus being rolled up (and, because of the shape of the blank, so as to establish a spout which gradually decreases in cross-sectional area along a portion of'its length andtoward What is to be its pouring end), the blank is die 'worked not only preferably to longitudinally" arch the spout along said portion of its length roams. ol. 222 -479) longitudinal central vertical section illustrating a modification, with here, also, the vent tube shown partially in ide elevation.

Fig. 8 is an end elevation, looking toward the left in Fig. '7.

Fig. 9 is, on still a further enlarged scale, a transverse section taken ,on the line 9-9 of Fig."7. I V v Referring nowto the drawings more in detail, and first to Figs. 1 to 6, the unit as here illustrated is shown as incorporating as its main structure a pouring spout l5, and as also including a vent tube I6, an annular flange l1, and a tubular cork I8.

The spoutl 5, as herein shown, is one rolled up from a thin sheet metal blankwhich was of the outline of a truncated triangle considerably attenuated in the direction of its altitude, thereby but also to providespecial formations at spaced points. along the spout for use infacilitating proper and secure attachment to the spout as said main structure.

For further comprehension of the invention,-

and of the objects and advantages thereof, referencewill be had to the following description and accompanying drawings, and to the appendedof the vent tube claims in which the various novel features of the invention are more particularly set forth.

In the, accompanying drawings forming a material part of this disclosure:

Fi 7, d awn Q-th same sc e asFis. 5; is. a

showing said unit with to provide a spoutof the relative length illustrated as compared with its larger and-smaller diameters at opposite ends. v i In thus forming the spout [5, it was also so die worked or otherwise equivalently worked as to become suitably longitudinally arched, between the prevised point of attachment of the flange I! and the end of the spout of smaller diameter. that is, the end thereof which is to be its pouring end. The meeting edges of said blank, when the spout is thus finally formed, lie along a line l9, while one of said edges is seen at Hiin Fig. 5. Preferably, said blank is so precisely cut, and the .die working thereof is so properly done, that a 'leak tight joinder of said edges is attained along spout l5 that, when the cork I8 is placed on the spout as shown in Fig. 1,

and so as then to have the end of the cork of greater diameter set squarely in the cup provided by said flange, the end of the cork of lesser diameter will project somewhat beyond the end of the spout of larger diameter, as indicated in dot and dash in Fig. 4. As will be understood, it is the last-mentioned end of the corkwhich, when the pouring-spout unit is to be attached to a bottle, is first entered into the latter at its-neck opening, preparatory to forcing the cork down tight into said neck, thereby to extend. well down into the bottle the portion of the vent tube projected beyond said end of the cork of lesser diameter.

The special formations on the spout [5 already referred to as employed for facilitating proper and secure attachment of the vent tube It to the spout, are two in number, as will appear hereinafter. These formations may be established, each in whole or in part, during the making of the blank of which the spout is to be formed, and/or during the forming of the spout from said blank, and/ or subsequently to the making of the spout except for one or both of said formations; in

accordance with methods well understood in the sheet metal working art. 7 r The air inlet end of said tube 16 is designated l6, and this end of the tube is slightly-upwardly canted as shown best in Fig. 5. Said end of the tube l6 extends into a recess at the exterior of the spout [5 established by an inward dimpling of the latter as at 20; ingress into said recess for the-vent tube iii being afforded by an aperture through the wall of the spout at said; dimpling, as indicated at 2!. This aperture 2:I' is of such shape and size that, when said end Hi of the tube [6 is forced therethrough to locate said tube end l'fi in said recess, the tube {:6 will. be girthingly gripped tightly and in aslealr' proof manner where it passes through said aperture, by the metal materialof the spout l5.

Said dimpling. 29 andjsaid aperture 21; together constitute one of the two formations on the spout l5 previously referred to as employed for facili tati-ng proper and secure attachment of the vent tube :6 to the spout.

The other of said two formations on the spout I5 is a' strip-dike portion of. the metal thereof, at the end of the spout of greater diameter, and bounded along one side; by a cut through the spout metal as indicated at 22; with said striplike portion forced down into the spout to estab--- lish a cradling strap 23 for the vent tube it well removed from the dimpling 2i} and alsowell removed from the end of said tube opposite to its end Hi As perhaps best indicated in Fig- 6, the strap 23- is so formed that it, and the spout; metal alongside the cut 22', combine to provide a meansintegral with the spout for tightly grip ping the vent tube l6, and consequently,.in com bination with the elements 20 and: 21, for holdingthe vent tube againstlongitudi'nal? mcv'ementrel'ative to the spout and" also against any shifting of said tube laterally thereof.

Soldering, brazing or-the like may be utilized at one or both of said two formations; but this may be dispensed with, to avoid the slight extra cost entailed, as not absolutely necessary. Referring to the modification of Figs. 7-,. 3 and 9,. here the parts to which are applied reference numerals with primes added correspond, respectively, to the parts to which have been applied the same reference numerals without primes. In this construction, however, the spout t5" is so formed that, starting at apoint at about where the dimpli-ng 20 would be placed, thespout. has a groove, extended along its length;. such groove, designated 24, extending. all the" way to: the: smaller or pouring end of the spout.

It will be noted that the end of said groove- 24 adjacent to the flange I11, isishap'ed as is: the end of the dimpling 20 adjacent to the flange if; and that the aperture 21' is placed at the lastnamed end of the groove 24 in accordance with the placement of the aperture 2| relative to the dimpling 20. J p

The vent tube 1:6 3 engaged by the. strap: 23'

and by the aperture 2| in the same way as already described in connection with the engagement of the tube l6 by the strap 23 and the aperture 2!, is of greater length than the tube l6. That is to say, the tube It, instead of having an upcanted end like the end [6 of the tube i6, is longitudinally prolonged beyond the aperture 2i, as at lfi to an extent equal to the length of the groove 2.4. This prolongation lfi of the vent tube is, furthermore, longitudinally arched for accommodation in, and for preferably tight fitting relation to, the groove 24.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United Statesv Letters Patent is:
